/**

 *
 * Demo Event handling using the Java 1.0 event model
 * Swing version
 * Note that the Swing controls do not participate in 
 * the queue based event model 
 * Swing controls are prefaced by J 
 * 	JButton, JLabel, JPanel
 * Old Style controls are simply: 
 * 	Button, Label, Panel
 * 
 * The methods action(Event, Object)
 *             handleEvent(Event)
 * are deprecated
 * 
 * Be careful - this is a strange mixture of old and 
 * new - your warranty is void befire you leave the showroom
 *
 * Use ^C  or kill -9 to quit
